The first way is using the entry positions selection within the linking tab. Within Fusion 360, there are a few ways we can do this. The solution to these problems is to have complete control of where our tool enters and exits our stock. Again, if we don’t have the option to move the entry point, our only option is to physically move the component more into the limits, if at all possible. Thus, a lead-in on the area out of limits would violate this, not allowing us to run the NC code. Likewise, with machine limits, our component may be on the limit. Which is, as well all know, an undesirable choice. Without the ability to control the entry point, our only solution would be to move the clamp itself. In this case, our toolpath may choose to lead in on a clamp. That said, it’s not uncommon for your clamps may be close to your component for maximum rigidity. We often use our machine envelopes to the maximum capacity, so every millimeter counts. Avoiding clamps, fixtures and staying within the machine limits It is this uncertain, timely, and expensive process that we can avoid by moving the entry positions of a toolpath. Even the most skilled polishers can damage the component deeming it unfit for use. Leading with outcomes that vary depending on the skill of the individual. Polishing marks out of components is a poorly controlled process. The process of removing witness marks is timely and expensive, requiring a skilled individual. A witness mark left on an outward-facing surface deems the component unfit for use. For visual reasons, the same applies here. For instance, if your tool leads into a face that is governed by a surface finish tolerance, the mark left from the lead may jeopardize the function of the component.Īdditionally, when creating components for the automotive industry, surfaces that are outward-facing have surface finish tolerances. Manufacturers often have strict tolerances to adhere to, dimensionally and from a surface finish standpoint. If we’re leading into a vertical face with the side of an end mill, there’s going to be a mark where the tool has led in. Let’s take a look at some potential scenarios: Controlling where the witness mark on the component will be Entry points of toolpaths – scenariosĬAM programmers need the ability to control the entry point of toolpaths for many reasons. The point at which your tool engages with the component is no different. When machining components, it’s vitally important for the CAM programmer to have control over all aspects of the toolpath, to ensure quality, efficiency, and safety. The ability to control the entry points of toolpaths is a must for CAM programmers.
